But before intelligence of the Livingstone Search Expedition at Zanzibar awaiting favorable weather, had arrived, the world was startled by the news that a private expedition, provided solely by the New York “Herald” newspaper, and in charge of Mr. Henry M. Stanley, had succeeded, after surmounting incredible difficulties, in reaching Ujiji, where a meeting of the most remarkable nature took place between the great explorer and the representative of the enterprising journal of New York. Unique in its origin, most remarkable in the accomplishment of its beneficent purpose, the Herald-Livingstone expedition had received the considerate approval of mankind, and Mr. Stanley had come to be regarded, and with justice, as a practical hero of a valuable kind. His accounts of his travels, his despatches to the “Herald” from time to time, the more formal narratives furnished by him, composed a story of the deepest interest and, when properly considered, of the greatest value. This interest has also been deepened and greatly strengthened by the later labors of Stanley in the great field made memorable by Livingstone; and in the results of later explorations we have it fairly demonstrated that the life-work of the elder explorer did not end with his death, but has fallen upon the shoulders of one in every respect qualified to carry on the good work. To fully appreciate the work done and to thoroughly comprehend its bearing upon Christian civilization, the reader will find in these pages a brief resume of the most important incidents in the life history of Livingstone, with accounts of his several explorations into the African continent. Hence, these, in connection with those of Stanley respecting his later researches, will serve to make a volume of extremely interesting reading upon a subject of universal interest to all Christian people.
